Definition
Monzogranite is a type of igneous rock and belongs to biotite granite rocks that are considered to be the final fractionation product of magma
Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine

Formation
Monzogranite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Picrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Monzogranite and Picrite Properties
Know all about Monzogranite and Picrite properties here. All properties of rocks are important as they define the type of rock and its application. Monzogranite and Picrite belong to Igneous Rocks.Texture of Monzogranite is Porphyritic whereas that of Picrite is Earthy, Rough. Monzogranite appears Veined or Pebbled and Picrite appears Rough and Shiny. The luster of Monzogranite is dull to grainy with sporadic parts pearly and vitreous while that of Picrite is subvitreous to dull. Monzogranite is available in black, grey, orange, pink, white colors whereas Picrite is available in black, brown, green, grey, pink, white, yellow colors. The commercial uses of Monzogranite are cemetery markers, commemorative tablets, creating artwork, curling, tombstones and that of Picrite are as a feed additive for livestock, as armour rock for sea walls, metallurgical flux, pottery, source of magnesia (mgo).
